Figure 3.

The difference in (a) body mass and (b) egg mass between focal females and females with relatively large and small combs. (a) Focal females, after controlling for differences in body size, were significantly heavier than females with smaller combs and significantly lighter than females with relatively larger combs (comb rank, F_1,16=10.14, p=0.006). (b) The eggs produced by focal females were of significantly greater mass when compared with females with relatively smaller combs and significantly lower mass when compared with those from females with relatively larger combs (comb rank, F_1,17=13.96, p=0.002).
